Ever since Southwest upgraded their gate areas with large HDTVs and leather chairs with power jacks, has anyone else noticed the people who are flying with other airlines crashing the Southwest gate areas? I've been seeing it a lot lately.

I have to say, it kind of annoys me a little bit. Only because it's premium seating and it's put there for the enjoyment of people who do business with Southwest. Also, as it is premium, it's also limited.. The "other airline flyers" who are intruding on the seating areas are displacing actual Southwest customers..

Would a posted sign that reads "Seating for Southwest Passengers Only" be out of line?

I'm curious to hear what other people think about this, or am I the only one even noticing it?
